Understanding Global Warming and Climate Change

The video explains the difference between global warming and climate change, focusing on the greenhouse effect and its role in maintaining Earth's temperature. It highlights human contributions to global warming through carbon emissions and discusses the resulting climate change effects, such as extreme weather events and rising sea levels. The impact on biodiversity, with species struggling to adapt or migrate, is also covered.

What is the primary role of Earth's atmosphere in relation to temperature?

• To act as an insulating blanket maintaining a stable temperature

• To reflect all heat back into space

• To block all sunlight from reaching the surface

• To increase the temperature by trapping all heat

How does the greenhouse effect maintain Earth's temperature?

• By cooling the Earth's surface

• By allowing all heat to escape into space

• By absorbing and re-emitting heat energy multiple times

• By blocking all sunlight

Which gases are primarily responsible for the greenhouse effect?

• Argon and krypton

• Helium and neon

• Carbon dioxide and methane

• Oxygen and nitrogen

What has been the trend in Earth's temperature over the past 100 years?

• It has fluctuated without a clear trend

• It has increased by almost a whole degree

• It has decreased significantly

• It has remained constant

What is the main difference between global warming and climate change?

• Global warming is a natural process, while climate change is man-made

• Global warming is temporary, while climate change is permanent

• Global warming refers to temperature rise, while climate change refers to long-term weather pattern changes

• Global warming affects only the poles, while climate change affects the equator

What are two main causes of rising sea levels?

• Melting ice and expanding warm ocean water

• Increased rainfall and river flow

• Decreased evaporation and increased precipitation

• Increased volcanic activity and tectonic shifts

How might climate change affect weather events?

• It will make them less frequent and less severe

• It will have no impact on weather events

• It will make them more common and severe

• It will only affect weather events in polar regions

What is a potential impact of climate change on biodiversity?

• Biodiversity will increase as new species emerge

• Species may struggle to adapt or migrate, leading to reduced biodiversity

• All species will thrive in new conditions

• No impact on biodiversity

Why might some species migrate due to climate change?

• To avoid human activity

• To find new food sources

• To escape from predators

• To find cooler regions as temperatures rise

What is a challenge faced by species unable to adapt quickly to climate change?

• They will migrate to urban areas

• They will evolve new traits instantly

• They may face extinction

• They will become more dominant
